A vacuum filter (Buchner funnel filtration set) is used to collect particulates (e.g., microorganisms, precipitates, crystals or suspended solids) from liquid samples. Under vacuum, liquid passes through the filter medium while solids are retained on the filter surface, enabling fast, clean and repeatable separation.

ROVAVF10 is a COLO.Science industrial vacuum filter set designed for routine laboratory filtration workflows. It combines a corrosion-resistant stainless steel Buchner funnel, a borosilicate glass suction flask, and a tight PTFE + glass discharge valve for reliable solvent/filtrate handling. A dedicated cleaning port supports easy maintenance, while lockable casters improve stability and mobility.
